Titanium oxide exists in three phases: cubic, anatase and rutile. The anatase phase transforms into rutile at 800°C. At this temperature, surface defects are created, predominantly O ion vacancies. This defect plays an important role in chemisorption. The sensing mechanism of titanium oxide is based on this chemisorption.
